Found this is the 2019 Ranger service manual.
Process is exactly what I tried and others have tried and succeeded.
Maybe some have customer spare key programming enabled. and I do not.

Service Manual said:Key Programming Using Two Programmed Keys
NOTE: A maximum of 8 ignition keys can be programmed to a vehicle equipped with a passive antitheft system (PATS).
1. NOTE: This procedure works only if 2 or more programmed keys are available.
2. NOTE: This procedure only works if the customer spare key programming is enabled.
3. Insert the first programmed passive anti-theft system (PATS) key into the ignition and turn the
key from the OFF position to the ON position (maintain the key in the ON position for
approximately 3 seconds).
4. Turn the first key to the OFF position and remove the key from the ignition.
5. Within 10 seconds of turning the key to the OFF position, insert a second programmed passive
anti-theft system (PATS) key into the ignition and turn the key from the OFF position to the ON
position (maintain the key in the ON position for approximately 3 seconds).
6. Turn the second key to the OFF position and remove the key from the ignition.
7. Within 10 seconds of turning the second key to the OFF position, insert the new,
unprogrammed passive anti-theft system (PATS) key into the ignition and turn the key from the
OFF position to the ON position (maintain the key in the ON position for approximately 6
seconds).
8. Turn the new key to the OFF position and remove the key from the ignition.
9. If it is desired to program additional keys, repeat steps 3 - 9 for each additional key.
